Poly(phenylene sulfide) (PPS) is well known for its heat resistance, high mechanical strength, excellent chemical
resistance, and good electronic properties. It is used in many areas, especially in electronics, mechanical, and chemical
engineering. In order to improve thermal and electrical properties of PPS as well as to expand its application, a series of PPSbased
nanocomposite films containing multiwalled carbon nanotube (MWCNT) of 0.1~10.0 wt% as functional reinforcing
nanofiller were manufactured by melt-mixing and -compression. The microstructures, thermal and electrical properties of the
nanocomposite films were investigated as a function of the MWCNT content. FT-IR spectra and SEM images confirmed that
PPS/MWCNT nanocomposite films supported that MWCNTs were randomly dispersed in the PPS matrix. DSC and TGA data
indicated that the thermal transition temperatures as well as the degradation temperatures of the nanocomposite films were
influenced by the presence of the MWCNT. The electrical resistivity of the nanocomposite films were dramatically changed
with increasing the MWCNT by exhibiting a typical percolation threshold. Furthermore, the applications of PPS/MWCNT
nanocomposite films as electric heating elements were demonstrated. The electric heating performance of the nanocomposite
films with high MWCNT contents was systematically characterized in terms of temperature response rapidity, saturated
maximum temperature, and electric power efficiency and operational stability at applied voltages up to 100V.
